[c-nsp] TE Config critique..

[Harold Ritter (hritter)]

You should include the "tunnel mpls traffic-eng load-share" command if
you want the traffic to be load-balanced proportionally.

Hi,

Would like opinions on the following lab TE config's - pro's/con's of 
using explicit v dynamic path selection? (In production env. our links 
are 8Mb + 4Mb respectively), and whether ip load-sharing per-packet is 
needed?(And basically any other "best practices" that I have neglected 
to use!) - Goal is load-balance  traffic over the 8Mb + 4Mb links.

Thanks in advance.
